Our Centerfire Cleaning Rod Guides are designed to insert into your action In place of your bold or bolt carrier. They feature a snout with a silicone ""O""-ring that inserts into your chamber, sealing the barrel off from the receiver. The ""O""-ring prevents solvents from leaking back into the action area and gumming up the trigger assembly. We currently stock ""O""-ring rod guides for over 1000 different action/cartridge combinations. Each rod guide is machined to fit specific actions and cartridge families from .17 up to .338 caliber. Unfortunately some rifle chamberings do not lend themselves to an ""O""-ring style rod guide, for these cartridges we recommend one of our Adjustable Cone Style Rod Guides.

In an effort to better serve the cleaning needs of our customers, we have upgraded our Sinclair ""O""-ring rod guides to include integral solvent ports. This upgrade is now included with every centerfire bolt action rod guide and nearly all AR style rod guides. If you prefer a rod guide without an integral solvent port, please contact us via e-mail or phone and we will happily provide you with a rod guide to your liking. These rod guides without solvent ports will be treated as semi-custom, so please allow 2-4 weeks for delivery of rod guides without solvent ports. There is no additional charge for rod guides without integral solvent ports.

If we do not inventory a rod guide for your specific action/cartridge combination, we can probably make it. These non-inventoried rod guides are considered custom rod guides and are a few dollars extra, please allow 4-6 weeks for custom rod guides.
